Chengdu, the capital of Sichuan Province in southwestern China, sits on the fertile Chengdu Plain, a region shaped by the ancient Dujiangyan Irrigation System—a 2,200-year-old engineering marvel that transformed the area into a thriving agricultural hub. Surrounded by mountains, the city is a gateway to natural wonders like the Tibetan Plateau and is about 1,640 feet (500 meters) above sea level. Its central location makes it a strategic base for exploring western China, including UNESCO sites like Mount Qingcheng and the Leshan Giant Buddha.
